To all whom t may concern:

Be it known that we, JAMEs SENIOR and HERBERT It. Boo'rs, Vcitizens ofthe United States of America, residing at North Sewickly township, inthe county of Beaver and State of Pennsylvania,` have invented certainnew and useful Improvements in Rail-Joints, of which `the following isaspecification, reference `being had therein to the accompanying drawing.j j

This invention relates to rail joints and the `object thereof `is toprovide a rail joint in the manner as hereinafter set forth forconnecting together' the opposing ends of a pair of rails and at thesame time `provide when occasion so requires for the expansion andcontraction `of the rails.

Further 4objects ofthe invention are to provide a rail joint whichshallbe comparatively simple in its construction and rangement, strong,durable, efficient in its use, readily setup in `operative position withrespect to the opposing ends of a pair of rails and further embodyingmeans to prevent the loosening of the clamping elements of the jointthereby preventing separation of the other elements of the joint andfurthermore the loosening of the joint.

With the foregoing and i other objects in view, the invention consistsof the novel construction, combination and arrangement of parts ashereinafter more specifically de scribed and illustrated in theaccompanying drawings, wherein is shown one form of the embodiment ofthe invention, but it is to be understood that changes, variations andmodifications can be resorted to which come within the scope of theclaims hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views: Figure 1 is a side elevation of apair of opposing rails showing the adaptation theretof of a rail jointin accordance with this invention, Fig. 2 is a sectional plan, Fig. 3 isa cross sectional view, and Fig. 4 is a detail illustrating a stopmember employed to prevent the loosening of a clamping member.

Referring to the drawings in detail, 1 and 2 denote ties upon which ismounted a rail chair, which is secured in position by hold-fast devices3, as shown, spikes. The rail chair is formed of two oppositely-disposedsections and as each of the sections is of the same construction, butone will be described,` the description of one applying to the other.rail chair comprises a rectangular base plate 4 having its upper face at`a point removed from its outer longitudinal edge formed integ-ral witha vertically-disposed abutment 5 ofthe saine length as the length of theplate 4 and which terminates in an upwardly inclined andinwardly-extending plate G of the same length as the plate 4 and whichin connection with the plate 4 and abutment 5 provides a pocket 7 forone side of the bases of a pair of rail sections. The plate G at itsinner end terminates in vertically-disposed fish plate 8 which has itsouter face provided with vertically-disposed spaced reinforcing portions9. The fish plate 8 is furthermore provided with a series of openings 10which project through the reinforcing `portions 9. The arrangement ofthe abutment 5 at a point inwardly ofthe outer longitudinal edge of theplate provides a flange 11, which is engaged by the hold fastdevices 3,the heads of the devices 3 engaging the abutment 5.

' The reference characters 12 and 13 denote opposing rails andisaidrails are mounted in the sectional chair, the bases of the railsengaging in the pockets 7, as clearly shown in F ig. 3 and are mountedupon the plates 4, these latter being so positioned as to be spaced fromeach other when the chair is set up. Each of the webs of the rails isformed with a series of enlarged openings 14 which are adapted to alinewith the openings 10 of the fish plates 8.

Extending through each set of alining openings 1() and 14 isv a threadedbolt 15 provided with a head 16. The bolts are alternately disposed withrespect to each other and each carries on its threaded end a clampingnut 17 provided with rigid teeth 18. The nut 17 is adapted to abutagainst the reinforcing portions 9 of the fish plates, whereas the headsof the bolts have interposed therebetween in the reinforcing portions 9,a disk 19 provided with a squared opening 20, which conforms to thesquared portion 21 at the headed end of the bolt 15. By such anarrangement the disk 19 is prevented from rotating upon its respectivebolt. Projecting from the disk 19 is a resilient stop arm 22, whichengages with the toothed portion 18 of a nut 17 to prevent Each 'of thesections of the back rotation thereof. The stop arms 22 are alternatelydisposed with respect to each other and the same arrangement is had withrespect to the nut 17; The openings 14 through which extend the bolts 15are of sueh diameter as to allow for the necessary contraction andexpansion of the rails when occasion so requires.

When the rails are supported by the chair, the fish plates 8 are of aheight as to engage the lower face of the head of the rails 12 and 13,as clearly shown in Fig. 3, and each of the fish plates is provided withan inwardly-extending portion 23, which abuts against the webs of therails.

What we claim is 1. A rail joint comprising the combination with a pairof rails, of a chair for supporting said rails and embodyinglongitudinally-extending flanges and integral fish plates provided withopenings, means engaging with said flanges for securing the chair inposition, alternately disposed headed bolts extending through theopenings of the fish plates and through the rails, alternatelydisposedclamping nuts mounted upon said bolts and provided with toothedportions, disks carried by the bolts and interposed between the headsthereof and fish plates and having squared openings to prevent rotationof the disk, and resilient stop arms alternately disposed with respectto each other and integral with said disk and engaging the toothedportions of the nuts to prevent back rotation thereof.

2. A rail joint comprising the combination with a pair of opposingrails, of a rail chair supporting said rails and provided with a pair ofintegral fish plates arranged in parallelism with respect to the webs ofthe rails and provided with openings, alternately disposed headed boltsextending through said openings and rails, and provided With squaredportions, alternatelydisposed clamping nuts mounted upon said bolts andengaging the fish plates and provided with toothed ortions, disks havingsquared openings, said disks mounted upon the squared portions of thebolts and int-erposed between the heads of the bolts and the fishplates, and stop arms projecting from the disks and alternately disposedwith respect to each other and engaging the toothed portions of the nutsto prevent back rotation of these latter.

3. A rail joint comprising the combination with a pair of opposingrails, of a pair of fish plates extending in parallelism with respect tothe rails and provided with openings, alternately disposed headed boltsextending through said openings and rails, alternately disposed clampingnuts mounted upon the bolts and engaging with the fish plates andprovided with toothed portions, disks mounted upon the bolts andinterposed between the heads thereof and the fish plates, andalternately-disposed stop arms projecting from the disks and engagingwith the toothed portions of the nuts to prevent back rotation of theselatter.

In testimony whereof We afiix our signatures in the presence of twowitnesses.
